Telemedicine: Economic and clinical evaluation of the management of ischemic stroke

2017

Summary Introduction Ischemic stroke (IS) is a therapeutic emergency that requires prompt care in a stroke unit (SU). In order to reduce regional inequalities and to promote uniformity in access to this technique, which is effective when carried out quickly, telemedicine-assisted thrombolysis was developed in Burgundy within the Telestroke system. At the moment, no study compared costs (i.e. expenditures) and revenues (i.e. funding) associated with the management of patients presenting an IS in Burgundy after the implementation of the Telestroke system according to the management strategy: patients undergoing thrombolysis directly in a SU or Tele-thrombolysis in a local hospital (LH) receiv…

Nitrous oxide fluxes from permafrost regions

2020

This dataset is a synthesis of published nitrous oxide (N2O) fluxes from permafrost-affected soils in Arctic, Antarctic, and Alpine permafrost regions. The data includes mean N2O flux rates measured under field (in situ) conditions and in intact plant-soil systems (mesocosms) under near-field conditions. The dataset further includes explanatory environmental parameters such as meteorological data, soil physical-chemical properties, as well as site and experimental information. Data has been synthesized from published studies (see 'Further details'), and in some cases the authors of published studies have been contacted for additional site-level information. The dataset includes studies publ…

Configurations spatio-temporelles des températures et des précipitations au printemps et en été 2003 en Bourgogne : mesures Météo France et simulatio…

2010

International audience; Contexte : En Bourgogne, un collectif pluridisciplinaire piloté par Alterre travaille la question de l'adaptation au changement climatique. Une confrontation entre deux saisons végétatives (1991 et 2003) sélectionnées comme étant représentantes des conditions moyennes actuelles (1988-2007) et futures (seconde moitié du xxie siècle) est développée sur la base d'une méthodologie multi-modèles (climatique, pédologique et hydrologique).Problématique : Au-delà des éléments connus (températures élevées et pluies peu fréquentes de 2003) l'étude vise à caractériser les écarts de conditions climatiques 2003-1991 sur l'ensemble du territoire bourguignon. Les températures de la…

DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY

2015

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…

Canopy Architecture Appraisal by Fractal Dimension of 'Flordastar' Peach Trees Grafted onto Different Rootstocks

2007

The objective of this research was to evaluate the modification of canopy architecture of ''Flordastar'' peach (Prunus persica L. Batsch) grafted onto rootstocks with different vigour, by the use of fractal dimension (D). The hypothesis was that different vigour rootstocks are able to modify the complexity of the branching pattern and that this effect can be assessed by a geometric parameter such as the fractal dimension (D) of the 2D projection of tree branching structure. The observations were carried out in a four-year-old experimental orchard of cv. ''Flordastar'' peach trees grafted onto Ishtara, Barrier, GF677 and MrS 2/5 rootstocks. On digital pictures of leafless, dormant peach tree…

Methods for evaluating causality in observational studies.

2019

BACKGROUND: In clinical medical research, causality is demonstrated by randomized controlled trials (RCTs). Often, however, an RCT cannot be conducted for ethical reasons, and sometimes for practical reasons as well. In such cases, knowledge can be derived from an observational study instead. In this article, we present two methods that have not been widely used in medical research to date. METHODS: The methods of assessing causal inferences in observational studies are described on the basis of publications retrieved by a selective literature search. RESULTS: Two relatively new approaches—regression-discontinuity methods and interrupted time series—can be used to demonstrate a causal relat…

The meaning of slow nursing in dementia care.

2015

Research literature in the dementia field lacks examples of ‘best-practices’ demonstrating concretely how it is possible to support the sense of coherence in people with dementia. The purpose of this study was to elucidate the nurses’ views concerning a caring approach that may support the sense of coherence in people with dementia. The data were collected through participant observation and focus group interviews during a four-month period in 2011. Sixteen registered nurses recruited from two Norwegian nursing homes participated in this study. The data were interpreted using a phenomenological-hermeneutical method. Three themes were identified: ‘being in the moment’, ‘doing one thing at a…
